1.下載yum 源

wgethttps://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm

# 鏈接在這里找https://dev.mysql.com/downloads/repo/yum/

2.安裝 yum 源

sudo rpm -Uvh mysql57-community-release-el7-11.noarch.rpm

3.顯示所有的 GA 版本

yum repolist all | grep mysql

4.選擇安裝的版本

sudo yum-config-manager --disable mysql57-community

sudo yum-config-manager --enable mysql56-community

如果遇到sudo：yum-config-manager：找不到命令

yum -y install yum-utils

yum repolist enabled | grep mysql

5.安裝

sudo yum install mysql-community-server

6.啟動(dòng) Mysql Server

sudo service mysqld start

sudo systemctl start mysqld.service

sudo service mysqld status

sudo systemctl status mysqld.service

7.MySQL Server Initialization (for MySQL 5.7 only):

A superuser account?'root'@'localhost'?is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command:

sudo grep 'temporary password' /var/log/mysqld.log

其他版本沒(méi)有密碼

8.修改密碼

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

可能會(huì)報(bào)一下錯(cuò)誤，5.7版本必須包含大小寫字母，數(shù)字和特殊字符
